HANGER FOR `LAMPS.

SPECIFICATION forming part of Letters Patent No. 769,072, dated August 30, 1904:.

i Application filed October 28,1903. Serial No. 178,875. (No model.)

To all whom t may concern:

Be it known that I, HENRY Gins'sEL, a citizen of the United States, residing at Wapakoneta, in the county of Auglaize and State of Ohio, have invented certain new and useful Improvements in Hangers for Lamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others` skilled inthe art to which it appertains to make and use the same.

Myinvention relates to a novel vconstruction in a hanger for street-lamps, the object being to provide simple and eiiicient means for hanging a gas-lamp over the middle of a road in such a manner that the same may be let down for purposes of cleaning and repairing and at the same vtime avoid the use of flexible tubing to feed said lamp; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure l is a view in elevation of a street-lamp hung over the middle of a road by means of devices constructed in accord ance with my invention. Fig. 2 is a fragl mentary detail view in elevation, on an enlarged scale, showing the elbow-jointbetween the feed-pipe and lamp and means for supporting said feed-pipe. Fig. 3 is a section on the line 3 3 of Fig. 2..

Referring now to said drawings, A and B represent posts at each side of a road or street and supporting a cable G at their upper ends. Adjacent one of said posts is a vertical gaspipe D, connecting with the underground main andwhich at its upper end is connected with a pipe E by means of an elbow-joint F. The said pipe E is connected at its other end with the feed-pipe of a gas-lamp Gr by means of an elbow-joint H, and said lamp is hung and supported by means of a cord or cable I, secured to a ring J at the upper end of the feed-pipe thereof and passing over a sheave K, supported on said cable C midway between the ends thereof, said cord or cable I being passed over a pulley L, mounted on the post B above the upper end of the pipe D, andsecured at its other` end to a windlass M, mounted on the lower end of said post B. On said pipe E, between the ends thereof, I mount a plurality of sleeves N, each secured in position by means of a set-screw O and provided with parallel flanges P, between which pulleys Q are revolubly mounted, which rest upon said cable I, so that the latter serves also to support said pipe E between its ends to prevent same from sagging. The said sheave K and pulley L are so mounted that said cable I when pulled taut will normally hang higher than the lowest points of said pulleys Q, so as to exert a lift onv the latter when taut.

While the ordinary elbow-joint used in gasiixtures might answer my purpose, I have found it advisable to use a speciallyconstructed joint R, which is better balanced and less apt to leak. The said elbow-joint R consists of a U-shaped member composed of two L-shaped castings l and 2, removably secured together, said casting l being hollow and provided at one end with an internally-threaded 'i nipple 3, adapted to receive the end of the pipe E and also provided at said end with a flange 4, provided with an opening for the passage of a screw 5, entering a threaded opening in the casting 2 for securing same to said casting l. Y At their other ends said castings 1 and 2 are provided with transverse openings 6 and 7, in which an X-shaped member 8 is journaled, one arm of. which consists of the ring J, hereinbefore referred to. The opening 6 in said casting 1 which communicates with the pipe E is surrounded at its ends by annular externally-threaded'flanges 9, adapted to receive the flanged washers l0, between which and the ends of said flanges 9 packing'll is interposed to form gas-tight joints, as will be obvious. The arm of said member 8 entering said opening 6 is provided with an annular groove l2, communicating with the pipe E and which is connected, by means of a transverse opening 13, with the longitudinal opening 14 in said arm, and this in turn communicates with a central opening in a third arm of said member 8 and therethrough communicates with the lamp. The flow of gas thus remains uninterrupted no matter what the relative positions of the pipe E and member may be. The' arm of said member 8 entering theopening 7 `is provided with an annular collar 15, bearing against the inner face of said casting 2, while its eXtreme end is provided with a short shank 16 and is tapped centrally to receive a screw 17, having a head larger than said shank 16 and which bears on a washer 18, inserted over said shank and bearing against the outer wall of said casting, said shank 16 and washer 18 being relatively so formed as to be incapable of relative rotation, this construction being commonly used in gas-cocks. The said elbowjoint R is also used to effect connection between said pipe E and thepipe D; but in said lastnamed joint the ring J is preferably omitted. rlhe said lamp is thus firmly supported, and by the same supporting means the pipe E is prevented from sagging. As shown in dotted lines in Fig. 1, the lamp may be easily let down for purposes of lighting, cleaning, and 'repairing same.. A stop-cock S may be provided in said pipe D to control the supply of gas to said lamp.

One great advantage of my invention is that it obviates the use of flexible tubing, which is a source of constant trouble and annoyance, and provides very simple and eifrcient as well as a more stable and ornamental v means for feeding and supporting the lamp.

'said lamp, swivel connections between said horizontal pipe and said feed-pipe and lamp, and pulleys on said horizontal pipe between itsends over which said cord is trained to support said pipe simultaneously with said lamp and prevent sagging thereof.

2. A hanger for gas-lamps comprising a sup* porting-postearrying substantially horizontal supporting means, pulleys carried by said post and supporting means, a cord trained over said pulleys, a vertical feed-pipe, an inflexible horizontal feed-pipe having pivotal connection with said vertical pipe and at its other end having pivotal connection with the lamp to be hung, connection between said cord and said lamp at one end of the former, and pulleys on said horizontal pipe between its ends over which said cord is trained to support said pipe against sagging between its ends, said pulleys on said pipe being lowerthan the pulleys on said supporting means and post.

3. A hanger for gas-lamps comprising a supporting-post carrying substantially horizontal supporting means, pulleys carried by said post and supporting means, a cord trained over said pulleys, a vertical feed-pipe, ahorizontal feedpipe connected at one end with said vertical feed-pipe and at its other end with the lamp to beA hung, connection between the latter and one end of said cord, and elbow-joints interposed in said connections between said horizontal pipe and said lamp and said feed-pipe comprising U-shaped members at the ends of said pipe, cross-armed members revolnbly mounted in the free ends of said U-shaped members and connected between their ends with said vertical feed-pipe and lamp respee tively, gas connection between said horizontal pipe and said lamp and feed-pipe through one arm of eaeh of said U-shaped members, and stung-boxes interposed in the connections between said gas-conducting arms and said cross-arms.

1n testimony whereof I aiiix my signature in presence of two witnesses.

HENRY GIESSEL.
